Problems solved by technology

Anti-static coating is a new type of coating that has been developed rapidly in the past ten years. However, although many anti-static coatings can achieve a certain anti-corrosion effect, it is difficult to achieve the purpose of anti-corrosion for a long time under sunlight or external force wear. , due to the characteristics of the coatings industry, environmental protection is also a very important factor
Road signs, street signs, billboards, etc. are placed outdoors. In the past, spray paint and ordinary powder coating were mainly used on the surface. Therefore, discoloration, chalking, and corrosion will occur within a short time after spraying, usually a few months. , fall off, must be replaced frequently, a waste of human and material resources

Abstract

The invention discloses an anti-static coating. The anti-static coating comprises the following raw materials in percentage by weight: 11%-20% of epoxy-terminated modified polyurethane resin, 5%-10% of titanium dioxide, 11%-20% of epoxy resin, 10%-16% of conductive zinc oxide, 5%-7% of superfine aluminum silicate, 3%-7% of aids, 5%-10% of pigments and the balance of water and inevitable impurities. The anti-static coating has good static electricity eliminating capacity, excellent scratch resistance, ultra-strong shock resistance and outstanding high temperature resistance; meanwhile, by adding a flatting agent and a curing agent which can be particularly matched with each other, a coated surface is relatively flat and smooth after a film is formed, and the appearance is attractive. Besides, by simplifying a preparation process, the manufacturing cost of the coating is lowered, and the anti-static coating is easy to use and generalize.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an antistatic coating. Background technique [0002] Conductive coatings refer to coatings that are applied to non-conductive substrates to enable them to conduct current and remove accumulated charges, called conductive coatings. Anti-static coating is a new type of coating that has been developed rapidly in the past ten years. However, although many anti-static coatings can achieve a certain anti-corrosion effect, it is difficult to achieve the purpose of anti-corrosion for a long time under sunlight or external force wear. , Due to the characteristics of the paint industry, environmental protection is also a very important factor. Road signs, street signs, billboards, etc. are placed outdoors. In the past, spray paint and ordinary powder coating were mainly used on the surface. Therefore, discoloration, chalking, and corrosion will occur within a short time after spraying, u...
